Introduction to Test Macros
- Now that you have written a reasonably-complex primitive it is time to test it.
- Test macros are the standard NeXtMidas way of testing primitives and intrinsics.
- Unit tests are used when testing libraries. (These will be covered later.)
- The NeXtMidas confidence testing tool will automatically run any test macros or unit tests.
```
nM> CONFIDENCE <OPT>
```
- Types of tests:
  - Non-interactive
    - These are preferred.
    - Require no user-interaction.
    - Done for numerical primitives.
  - Interactive
    - Only run with CONFIDENCE/INTERACTIVE or if test macro is run manually.
      - Usually have a "if interAct then" section.
    - Require user interaction.
    - Requires graphical setup for test to run.
    - Done for graphical primitives and primitives that require a user to inspect the output.

X-Midas Users Take Note:
Testing primitives is easier in NeXtMidas than it is in X-Midas. Use of macro tests is common throughout the NeXtMidas SYS option tree and also done in many user-created option trees.
